APC patterns are stored in the firmware (rom) of the machine kn2000
1) if you copy a pattern to ram (function COMPOSER COPY) there is no room for variations even in EXPAND mode
2) if you use APC patterns while recording parts in the sequencer, they won't be saved with the SAVE FILE function (only the key you hit to start accomp (e.g. notes 'C' 'E' 'G' in pianist mode)
(in Tech file format they store pointers to APC ROM)
3) BUT there is a way ...
link a pc to the kn2000 and map tracks to channel (BASIC CHANNEL) and record any pattern. You can listen, edit and modify patterns.
I have done this myself, it works, for years.
You store your new ACCOMP in a composer memory, and have (EXPAND MODE)
1 memory for Normal style
5 memories for Variations
1 Intro
1 Fill in 1
1 Fill in 2
1 Ending
you map your song to the panel memory to change Variations while playing
Home it helps
